1) A 0.464g sample of compound containing the elements carbon, hydrogen, oxygen, and sulphur was burned completely, yielding 0.969 g CO₂ and 0.198 g H₂O. In a separate experiment, all the sulphur in another 0.464 g sample was converted to 0.859 g of BaSO₄. What is the empirical formula of the unknown compound?

2) Ethyl alcohol, C₂H₅OH, is a fermentation produce of sugars in the presence of enzymes. How much glucose, C₆H₁₂O₆, would you need to start with to prepare 4.6 x 10⁴kg of ethyl alcohol if the yield in the reaction is 64.5%?

The equation for this reaction is

C₆H₁₂O₆ + 3O₂->4CO₂ + C₂H₅OH + 3H₂O

3) A solution containing 40.7g of calcium nitrate in a volume of 0.500 L was prepared.

a. Calculate the number of moles of calcium nitrate in this solution.

b. Calculate the number of molecules of calcium nitrate in this solution.

c. Calculate the total number of ions from the calcium nitrate in this solution.
